For Pam, If you can post emails to anyone else,(which it seems evident thatyou can do) your system is probably ok. The problem may lie on whatever processing the list server does to determine whether you're a member of the list or not. I would try opening a yahoo email account, try to subscribe to the Berner-l from that address then try to post something. If the system accepts you from that address then you know that it is something on prairie-net's side of the fence that's messing up the hand off.
